2. 有問題的句子的列舉
考生寫的句子容易出現(xiàn)三個問題：一是使用破碎句，二是使用接連句，三是句子連接不正確。
1）。 破碎句
所謂破碎句，就是句子不完整，通常是沒有謂語（或者說謂語是動詞的非謂語形式，如分詞），或者是從句單獨成句。
破碎句：She singing alone. （無謂語，singing是現(xiàn)在分詞）
正確句：She is singing alone.
破碎句：He did not come. Because he was sick. （從句單獨成句）
正確句：He did not come because he was sick.
2）。接連句
所謂接連據(jù)，就是兩個句子直接連在一起，既未使用連詞，也未使用正確的標點符號。
接連句： Professionals such as lawyers or accountants usually work longer hours than factory workers they have greater freedom in planning their time.
正確句一： Professionals such as lawyers or accountants usually work longer hours than factory workers. However， they have greater freedom in planning their time.
正確句二： Professionals such as lawyers or accountants usually work longer hours than factory workers; however， they have greater freedom in planning their time.
3）。句子連接不正確
所謂句子連接不正確，就是兩個獨立的句子之間以逗號連接，這是不合英語語法的。正確的做法是以連詞、分號、冒號、句號等連接兩個句子。
不正確句： Breaking chalk into two pieces is a physical change， there is no change in the composition of the chalk.
正確句： Breaking chalk into two pieces is a physical change， so there is no change in the composition of the chalk.
II 高分表達
除了在句式上長短句相結合準確表達外，朗閣海外考試研究中心建議新托?？忌褂靡恍┨厥獾木涫剑允咕湫投鄻踊?。句型多樣化也是作文得到高分的條件之一。除了我們之前經(jīng)常提到的高分句式，如倒裝句、強調(diào)句、狀語前置、插入語等，筆者還提出另外一個句式的多樣變化，即主語多樣化。下面筆者將列舉幾個句子概括介紹前面四種句型，而重點分析主語多樣化。
正常句： Luck only works in extreme cases.
倒裝句： Only in extreme cases does luck work.（否定詞位于句首的倒裝。）
正常句： The internet provides people access to the latest information.
強調(diào)句： It is the internet that provides people access to the latest information. （強調(diào)the internet）
正常句： The environment has been deteriorating severely along with the development of industry.
